M14 Day 2

Thermocouple are always connected in what to ensure they measure the average exhaust gas temperature?

• Series

• Parallel

• Parallelogram

Thermocouple extension leads are always made from what?

• Same material as thermocouples

• Different material than thermocouples

• Gold and alumel

• Titanium and chromel

Thermocouple compensating leads are used for what?

• transmit the thermocouple signal to the indicator

• transmit thermocouple temperature to the gauge

• transmit something to somewhere via somewhere else

In order to obtain a standard output, and reduce the indicated temperature to

a common factor for a given engine speed we use what?

• Ballast resistors

• Extension lead

• Trimming resistor

With the passing of time, the compensating leads in the circuit will create

an increase in resistance value due to natural ageing, what would we use to combat this?

• Trimming resistor

• Manscaped 4.0 trimmer

• Hedge trimmer

• Ballast resistor

When testing thermocouple systems the test set contains what sort of conversion chart to set up and calibrate the system/indicator?

• Temperature/millivolt

• Temperature/microvolt

• Temperature/ampare

• Temperature/megavolt

With reference to EGT indications, what is the EGT always measured in?

• Kelvin

• degrees Fahrenheit

• degrees Celsius

The maximum temperature limit of EGT that should never be exceeded is usually a line of what colour?

• blue
• amber

• red
• yellow

The maximum EGT

for the maximum continuous thrust setting, that can be exceeded for a short time (take-off, go-around etc) is indicated by what colour line?

• Amber

• Red

• Green
• Blue

In servo operated temperature indicators what acts as a variable reference to allow either a positive or negative signal to

drive the servo-motor depending on which is the greater signal?

• Positional feedback

• Positive feedback

• Negative feedback

• Feeder backerer
